Gyro noise vs bias

Easy · Whiteboard

A gyro has random noise with standard deviation 0.5 °/s per sample and a constant bias of 0.2 °/s. (a) If you average 100 samples, what is the noise on the average? (b) If you integrate the gyro to get heading, how far off is the heading after one minute from the bias alone? What does that tell you about fixing each problem?
